Hot dip plastic coated steel pipe features corrosion resistance, no scaling, and low fluid resistance

Description :

　　There are three common methods for connecting coated steel pipes, namely threaded connection, flange connection, and groove connection. Threaded connection is a traditional form commonly used between DN15-100 pipes. The connection technology includes multiple steps such as threading, deburring, chamfering of plastic lined pipes, cutting, anti-corrosion of screws, and connection. The length of the threading varies depending on the use of the pipe fittings, but one thing is the same, which is to ensure that the end face of the pipe touches the silicone rubber at the root and conforms to the formation of a secondary seal. Its specific properties can make it the new favorite of the pipe industry in just over a decade. Prove that the pipeline has the following properties: good temperature resistance of the coating, long-term use in an environment of -40 ℃~300 ℃, no combustion or softening phenomenon, high strength, tested pressure up to 5.5Mpa at room temperature, low fluid resistance, no scaling of the pipeline, improved transportation efficiency, and resistance to acid, alkali, and salt corrosion. There are also many details to pay attention to in the processing technology of fire protection coated composite steel pipes, and the pipeline will not rust within 70 years.

　　In the current construction of residential areas, many wires are used, which also require protective layers. However, the danger of steel pipes is high, and plastic pipes are not used for a long time, so coated steel pipes are more suitable for protecting wires. The efficient insulation of polyethylene makes the use of wires safer, and coated steel pipes can isolate wires from the environment, so wires will not be affected during use. The power supply environment of residential areas will also be safer under the protection of coated steel pipes, so coated steel pipes are also a safe pipeline for daily life.

　　FBE coatings come in two types: single-layer and double-layer. The so-called FBE coating generally refers to a single-layer fusion bonded epoxy coating. The single-layer FBE coating uses specialized fusion bonded epoxy powder coating as the film-forming material. Use electrostatic spraying technology to apply epoxy powder coating and form a film in one go. This epoxy powder coating is a thermosetting coating made by mixing and breaking solid epoxy resin, curing agent, and various additives. The coating process of double-layer fusion bonded epoxy powder coating is relatively simple, and only minor adjustments can be made on the basis of the original single-layer fusion bonded epoxy powder spraying equipment, that is, dividing the spray gun into three groups, and spraying the bottom layer powder in the first group. The external coating of internal and external epoxy powder anti-corrosion steel pipes (FBE/2FBE) is a new type of anti-corrosion layer. The second group of sprayed outer powders adheres to the compatibility function of single-layer FBE coating with cathodic maintenance, and will not trigger cathodic maintenance barrier. The heat resistance and anti-corrosion of cold and hot circulating water pipelines can be applied to pipeline anti-corrosion in seawater circulation systems and chemical systems. It has strong corrosion resistance, drag reduction, anti-corrosion, compression resistance, antibacterial and other effects, and has good chemical stability and water resistance. It is generally not restricted by the conveying medium, and there are no worries about "running, emitting, leaking, or cracking". It is widely used in fluid transportation in urban construction water supply, fire protection, petroleum, gas, chemical, sewage, mining, agricultural irrigation and other fields, to replace high energy consuming, easy to rust, scale, short service life, and bulky cast pipes.
